DEVICE FOR TRANSMITTING COMPRESSED AIB. TO AUTOMOBILE TIRES.

Application led November 26, 1917. Serial No. 203,927.

To all whom it may concern:

' Be it known that I, LLOYD W. DILwEc, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of .Wisconsin, have invented new and useful Improvements in Devices for Transxnitting Compressed Air to Automobile Tires, of which the following is a specification.

One of the primary objects of my present l0 invention is to provide a device for conveying com ressed air from one pneumatic tire to,anot er.

I have found by experience that Vit some- 4 times occurs that the compressed air escapes from one or more of the inflated'tires of an automobile wheel, and such tire becomes deflated, while some of the other tires remain inflated, and sometimes, owin to the expansion of air therein, such tires ave an excess of pressure which should be permitted to esca e. Theobject of my present invention is therefore to provide a simple and eicient means of transmitting com- Like parts are identified bythe same reference numerals thruout the several views.

1 represents one of the front wheels of an automobile having a pneumatic tire. 2 is one of. the rear wheels of such automobile. 3 is a flexible tube thru which an excess of air is transmitted from the front to the rear wheel, or any other wheels of a vehicle, as circumstances may require. The tube 3 is preferably made of rubber, andthe same is connected with wheel 1 thru the sleeves 4 and 5, disk 6, said disk being provided with apertures 7, rod 8, guide 9', valve 10, disk 11, rod 12, spring 13, guiding bracket 14 and connecting sleeve 15, whereby-air is led, as indicated by the arrow 16, to the opposite end of said tube 3 when it passes into the deilated tire of wheel 2, thru the-sleeves 17 and 18 and coupling 19, thence around the valve stem 20, when it passes down past the other valve 21. The valve 21 is supported on the disk 22, and said disk 22 is supported bythe rod 23. Interposed bepressed air from one pneumatic tire'toan-,ftween the d1sk22 and the bracket-24 is a 25 other, whereby' I am enabled to inflate a deated tire without using a pump when on the road or in the country where comipressed air cannot be conveniently supplied, while compressed air may by my device be transmitted from any one or more wheels to any one or more other wheels, regardless of the locationof such other wheels, or whether such wheels form part of the same vehicle -or not. I have for convenience of illustration shown one of the front. wheels of an automobile connected with one of the rear wheels'of such vehicle.

My invention is further explained by reference to the accompanying drawing, in 40 which- Fi re 1 represents a side view of an automo ile, provided with my device for transmitting compressed air from one pneumatic tire to another.

Figure 2 is a side view, mostly in vertical section of a simple device for connecting a iexible tube with one of the wheels having asurplus of compressed air.

Figure 3' is a similar view to that shown in Figure 2, showing the device located at the opposite end'of said Hexible tube with a pnumatic tire whichv has become deflated, an

Figure 4 is a transverse section of the de- 55 vice drawn von line` 4.-4 of Figure 2.

' of the sleeve 15 the shoulder 7 is brought in spiral spring 25, which spring is adapted 8 by its recoil to hold said valve 21, when not forced open by the incoming air, to its seat. The coupling 19 is connected with the pneumatic tire of the wheel 2 thru the sleeve 26, whereby when said wheels 1 and 2 are connected together, as shown in Figure 1, compressed air may be readily led from the pneumatic tire on said wheel 1 to the pneumatic tire on said wheel 2, or from any pneumatic tire having a surplus of compressed air to any tire having a less supply of compressed air.

It will be understood that as the sleeve 5 is turned down on the threaded end 6 contact with the upper surface`of the disk 6, whereby said disk and the rod8 are moved downwardly, and whereby the valve 10 is opened.

' My invention will prove to be very useful in such emergencies as may arise, wherein the motorist discovers that he has a dellated tire and is without a reserve air supply container or a fpum which may be used to restore the de ate tire. Such emergencies usually occur when the motorist is out on the road and not within access to a compressed air supply, and often imposes upon the motorist the dut of a disagreeable trip in quest of relief. y invention is de- U0 ferring it to the deflated tire. By means of.

usual pressure gauges, itmay be determined when the reduction of pressure in the full tire has reached the point of safety. If necessary, the other tires in the equi ment may be drawn on for a contribution o compressed air, as` before, so that the pressure may be e ualized in the set of tires. By means of t 1e emergency device whichI have devised, a disabled -motoristl will be enabled to reach a station where permanentA reliel may be secured, without sufferin the delay, inconvenience and damage whic 1 otherwise would be encountered.

Having thus described-my invention what I claim-as new and desire to secure by Letters Patent, is

v1. The process herein described for transmitting compressed air fromv an inflated automobile tire to a relatively deflated tire, consisting in connecting such tires together with an air tight duct, and permitting the highly compressed air to pass through such 'duct from the inflated to the other tire.

2. The processtherein described for transmitting compressed air from an. inflated automobile tire to a relatively deflated tire, both connected with the same automobile, consisting nconnecting such tires together with an air tight duct, and permitting the highly compressed air to pass through such duct from the inflated to the other tire.

3. In an automobile, means forptransmitting compressed air from an inflated tire to one which is relatively deflated, the said means-comprising a tube for connecting the tires, each of the latter being provided with a normally closed inlet valve and a stem for operating the same against the confined air pressure, the said tube being provided at one end with means for engaging the stem of the inflated tire to open the valve therein to permit the flow of air from the inflated to the deflated tire. n

4. Means for inflating pneumatic tires, wherein one pneumatic t1re contains ater air pressure than another pneumat1c tire, and wherein air from the first named tire is transferred to the second named tire a flexible conduit, a coupling at each end of the conduit for attachment to the tire valves, said couplings permitting deflation and in- -flation of the tires for equalizing air pressure in the tires.

5. Means to utilize the compressed air contained in a pneumatic tire, comprising a flexible conduit, and a cou ling at each end of the conduit, one of sai couplings bein designed for attachment to the valve of sai tire, and constructed to control the passage of air through the conduit.

6. A device for equalizing the pressure in tires, com risin a conduit having terminal members orme to be placed in connecting engagement with the valve nipples of two automobile tires, one of said terminal members being provided with a valve unseatin device for unseating the valve of o ne of'sai tires to permit air pressure to flow from that tire through the conduit and into the other tlre.

7.. That method of equalizing the pressure in pneumatic tires which'consists in placing the interiors of the tires in communication with each other through a conduit.

In testimony whereof I aflx my signature in the presence of two -witnesses.
